How to listen to the lungs with a stethoscope What is the method

Lung auscultation learning software.

(1) Breath sounds, you should be familiar with the characteristics of the three breath sounds. During auscultation, pay attention to the nature of the voice and the intensity of the voice, the pitch and the length of the phase during the inspiratory period.

Bronchial breath sounds are similar to those produced by raising the tip of the tongue and opening the mouth to exhale air"Hah" ("ha") tone. It is characterized by a longer expiratory phase than the inspiratory phase, a stronger tone, and a higher pitch. It is normally audible in the larynx, suprasternal fossa, back 6 and 7 cervical vertebrae, and near the 1st and 2nd thoracic vertebrae.

Alveolar breath sounds: similar to those produced when the upper teeth bite the lower lip and inhale'husband" ("fu-fu"The sound is soft, like the sound of a breeze. It is characterized by a sound that is longer than exhalation, strong and high-pitched, and short, weak and low-pitched during expiratory periods, which can be heard in both normal lung fields.

Bronchoalveolar breath sounds: characterised by inspiratory sounds that resemble alveolar breath sounds, but are higher pitched and louder. Expiratory sounds resemble those of bronchial breathing, but are weaker in intensity.

The pitch is slightly lower. The sounds of inhalation and exhalation are almost equal in time, degree and pitch. Normally, this sound can be heard in the 1st and 2nd intercostal spaces on both sides of the sternum, at the level of the 3rd and 4th thoracic vertebrae in the interscapular region, and in the anterior and posterior parts of the lung apex.

2) Rales: dry rales. Wet rales.

3) Voice resonance, ask the patient to resonate**"yi"Long sounds, while auscultating in symmetrical parts of the chest, can normally hear soft, indistinct sounds, syllables are indistinguishable.

4) Pleural friction rub: When the pleura is inflamed, the surface of the pleura is rough, which is similar to the sound heard by covering the ears with one hand and rubbing the hands with the fingertips. It is most common on both axillary sides.

Dizzy, I'm afraid this question was raised by people in our industry... Everyone's diagnostics ???

Inaudible. The main function of the stethoscope is to hear whether there is pneumonia, but the accuracy of the stethoscope is not too high, and it can roughly judge whether there is pneumonia. If pneumonia is to be confirmed, a chest x-ray and routine blood tests are done.

If the stethoscope is not good at judging the type of disease, then it is necessary to go to the hospital for a chest x-ray. If you have pneumonia**, you also need to use antibiotics and drugs to suppress cough and reduce phlegm, so that you can control the condition, and pay attention to keeping warm and avoiding cold.

Precautions for using a stethoscope.

When used, the auscultation head diaphragm must remain intact and must not be loosened.

When not in use, the stethoscope should be placed in a dry and ventilated room, and it is strictly forbidden to contact acid, alkali or corrosive materials, so as not to corrode the equipment and shorten the service life.

The ear part of the stethoscope must be frequently wiped and disinfected with alcohol to prevent contamination.

There are a lot of questions. Not to mention the heart, liver and kidney of the left hand, nor the lungs, spleen and kidney of the right hand, let's briefly analyze some common pulse signs in general.

The nature and location of the disease can be determined first.

Generally, the pulse of cold disease is tight, heavy, and slow. Most of the febrile venereal diseases are acute and forceful, and weakness is a deficiency disease.

If it floats (you can touch it lightly), it means that the disease is on the surface, and if it is sinking, it can only be touched by force, indicating that the disease is in the inside, or it is dirty.

Second, it can be inferred that some diseases advance and retreat.

If it was originally a symptom and the pulse was floating, but the pulse gradually became swollen and the fever was high, it means that the evil is flourishing and the main disease is advancing. If it gradually eases from Hongda, that is, the disease gradually improves.

In addition, the stethoscope knows that the heart is hot, this is generally not a stethoscope, of course, the patient with a hot heart must have a rapid heartbeat. Therefore, even a single pulse can also signal a loud pulse, rapid and fast.

If the blood circulation is not good, it can be manifested as a weak pulse or astringency like a blade including bamboo.

That's all, I hope I can help you.

Abnormal breath sounds that can be heard with a stethoscope include sputum sounds, crackles, rales, wheezing, tubular breath sounds, pops, decreased breath sounds, and so on.

Lung infections are crackles and sputum sounds, and if the sputum is particularly viscous, there will be a dry rale.

Acute pulmonary edema is a large number of crackles.

Pneumothorax is a decrease in breath sounds or, in severe cases, absent breath sounds.

Tubular breath sounds occur if a cavitation of the feenec is formed due to various diseases (tuberculosis, conventional bacterial or fungal infections).

Crackles are seen in diseases of alveolar hemorrhage, such as vasculitis, rheumatoid lung, and so on.

Atelectasis is also the absence of breath sounds.

Pleural effusion is a decrease or absence of breath sounds.
